Re: What's the problem?
If their share price (up 20% in the last year, more than 200% in 5 years) and the quarterly profits are anything to go by, bankruptcy appears to be some way off.
If they are doing well now, with W10 having had such a hard time and being cheap to say the least, then the future - new machines (people and companies do still buy them), new phones, new Surfaces, all running on what is a very stable platform - looks even better.
Of curse, the current share price could be because others see that future and therefore it is required to be good simply to retain the current levels.
Of course, we may well be in a share bubble (again) because of low interest rates. Certainly the case with houses here (in the UK).
